The present invention is addressed in a specific sense to window sashes made of metal and the object is to provide a simple, novel and effective means for holdingthe glass in place in the frame, said means, furthermore, being so constructed that it acts as an effectiveretainer for the putty. V

{In the structure shown .a metal window frame is employed having side walls 10, a

i i top wall 11, and a sill 12. The sidewalls are provided withgui'de slots 13, in which are engaged the wings or flanges 14 of an erence numeral 15, and a lower sash designated 16.v As these sashes are generally of Y the same formation, corresponding partsare given similar reference numerals. I

Eachsashcons sts of metal stiles 17, whose '4 outer margins form the said guide wingsor of the stiles 17 (see Fig. 7.) The two stiles- 17,.are connected byatop rail 20, and a bottom rail 21, which respectively have oifset portions 22 and 23, forming open-sided rabbets 24 and 25, for the reception of the upper and lower ends of the glass, 26.

Thev lower end of the lower sash, 16, has a plate 27 secured to its lower rail 21, and extending over the open side of the "rabbet 25, thereby forming a groove of said rabbet.

This plate 27, has an inturned portion 28, I

constituting a stop for the sash that abuts the sill 12. The lower rail 21, of the upper sash 15, also has a plate 29. secured to it, said plate extending upwardly across the open side of the rabbet 25, to form a groove of saidrabbet. This plate is then inturned as shown at and is provided witha longitudinal depression or groove 31: The upper rail of the lower sash 16, has an outwardly turned flange 32 along its upper side and detachably mounted on said flange and covering the said rail 20, is a'channeled capplate 33, held in place by screws 34, and thefasteners 35 of" the usual lock or latch 36. This cap plate flange'37, that enters the groove: 31, ofithe 33, has along its outer edge a down-turned p endi ng-flange 38, that overlies'the open side of-th-erabbet'24.

- The upper rail 20 other fastenersia' glass retaining plate 40. that I I I I of the uppersash 15, has secured-toits inner side by screws 39 or overlies the open side of the rabbet 24, of said railu Theupper edge ofthe plate 40, haszan inturned flange 41. Sprungo'ver this flange is channeled shield-42,015 suitable metal The inner sides of'thestiles 17 of each sash t have secured thereto, preferably by electric welding, keeper strips 44, which it will be noted are wholly" outside "the rabbets .19.. I

These strips have inset portions 45, spaced from the stiles 17 forming channels or grooves'46. It will be noted that'the offset portions 45 extendaway from the rabbets'19. Glass retainer strips 47 overlie the cap strips 44 and145." Theirouter margins are reversely bent'into'inturned flanges forming hooks :48,

that laterally slide'into and outof thefchan- 9 nels 46 beneath the portions' 45 of saidcap strips 44.7 When so engaged, a's'shown" in Figure 3' the said retainer strips. extend over .the op n sides r. therjabbets' 1 9, and their a inner margins are reversely bent into in;

slid inwardly, the putty being placed so as turned flanges 49, that overlie the margins of the glass and are in line with the portions of the keeper strips 44, which are welded to the stiles 17. The usual putty 50 is placed around the glass and fills into the space between the flanges 49 and keepers 44, thus looking the-retainer strips in place said retainer strips in turn interlocking with the putty and holding the same against dislodging.

In glazing'the lower sash-of theembodiment of the invention disclosed, the cap 33 is detached andthe glassretainerstrips 47 are removed. The lower edge of the glass 26 is then dropped into the groove 25 of the lower rail Qland said glass is then swing laterally throughthe open sidesofthe rabbets 19 and 24. Theputty is then appliedand the glass retainer strips 47, are then engaged beneath the portions l5,-of the keeperstrips and are to be forced into the space within the-said retaining strips 47. IN hen the putty li ardens the entire structure will be interlocked and held against displacement aswill be clear by reference to Figure 7. Thecap strip 38 1s thenplaced in position and fastened, thereby securing the glass effectively in place, Similarly. theupper sash is glazed. The top retainer strip 40,,being removed and theglass retainer strips 47, thereof, being detached, thuspermit the insertion oft-he glass after which the parts are returnedtoposition and secured.

VVh-at Iclaim is: p

Ina window sash structure, ai'sash frame having an open sided glass-receivin rabbet, akeeper located on the side of the frame on which the open side of the rabbet is located 7 and having a portion spaced from the frame and extending away from the rabbet, said keeper being located outside the rabbet, and a glass retaining member having a hooked portion that slides laterally parallel to the frame to a position beneath'the retainer on the movement of the retaining member toward the 'rabbet and having a portion extending over the rabbet when the hooked portion is behindthe keeper, said frame having an unobstructed portion behind thekeeper to permit the glass retaining member to slidetoward and from its position over the rabbet and in a path substantially parallel tothe side of the frame.

2. Ina window sashstructure', a frame bar com risin a late havin offset. ontions one of which forms the body of:the bar,,.the other being offset. therefrom and providing; an. open sided glass-receiving rabbet along the inner edge of said body portion, a-keeper strip on thes-ide of said body portion on which the open side ofthe rabbet is located and being disposed wholly outside said rabbet, and a glass retaining strip slidable transversely along the face of the body portioninto and out of interlocking relation with the retainer strip and to and from a position over the open side of said rabbet.

3. In a window sash structure, a window sash including a stile formed of a plate having substantially parallel offset portions, one of which constitutes a guide wing that slides in the frame, the other forming the wall of an open-sided glass-receiving rabbet, a hooked keeper strip carried by the portion of the guide wing and disposed longitudinally along and adjacent to the open side of the rabhet, and a glass-retaining strip that is slidable along the face of the wing portion and engages behind the keeper strip, said retaining strip when so engaged, projecting overrth e' open side of the rabbet.

iQIn a window sash structure, a window sash includin a stile formed of a plate having substantia ly parallel offset portions, one of which constitutes a guide wing that slides in the frame, the other forming the wall of an open-sidedglass-receiving rabbet, a hooked keeper strip carried by the portion of the guide vwingand disposed.longitudinally along and adjacent to the open side of the rabbet, said keeper strip having its hook portion spaced from the wing and extending away from the rabbet,'and a glass-retaining strip having a hook portion along its rear side that is movable along the faceof the wing portion and engages behind the keeper strip and extends thereover and over the open side of the ra'bbet.

5 In a windowisash structure, a window sash including a stile-formed of a plate having substantially parallel ofiset portions, one of'which constitutes aguidewing that slides in the frame, the other forming-the wall of an open-sided glass-receiving rabbet, a hooked keeper strip carried by the portion of the guide wing and disposed longitudinally along and adjacent to the open side of the rabbet, said keeper strip having its hook portion spaced from the wing and extending away fromthe :rab-bet, and a glass-retaining strip having a hook portion along its rear side that is movable along the face of the wing portion and engages behind the keeper strip 'andextendsthereover and over the open side of the rabbe't, the free side of the glass retaining stri having an inwardly turned portion pro-vi 'ing a putty retainingfiange.
